It's been awhile since I posted here but in the past, all the information I've received here has been top-notch quality and swift.
Very professional and very useful site.

However, now I've encountered a very odd problem, not with Excel, but rather with regard to Wi-Fi networking.

I've already done quite a bit of diagnostics and troubleshooting - all to no avail.

I'm looking for some type of networking support forum, similar to this forum, where there's a lot of very wi-fi knowledgeable people willing to assist, similar to this what this forum is with regard to Excel.

I've done some looking but can't really find anything that isn't really masquerading as a paid support site or doesn't have any volume of posts.

Anyone here know of a good, old-school, support forum for Windows Wi-Fi networking?

For explanatory purposes, here's a description of the problem which i posted in the Microsoft's Windows Community (with no answers received).

(it's not letting me post the link)

Lenovo T520 Laptop
Dual Boot to Windows 7 Ultimate (not OEM).
Partition 0 is Windows 7 Ultimate x64 (main usage for the laptop)
Partition 1 is Windows 7 Ultimate x86 (hardly ever used - almost never)
Partition 2 is Storage

I told my son (who is the primary user of this laptop) to connect to the internet with a network cable I gave him when we moved into this location (5 years ago).
However, about 1.5 years ago my son told me he couldn't connect to the internet anymore.
When I investigated it turned out he never was using the ethernet cable because the ethernet cable I gave him was defective.
He never told me it wasn't working but instead he was actually connecting via Wi-Fi.
So the points here are 2:
1. For a long time, the W-Fi was working fine at this new location, and
2. About 1.5 years ago it quit.

To manage the issue as simply as possible, I just got him a proper ethernet cable and he was back online - problem solved.
I did not spend much time investigating the issue with the Wi-Fi for reasons which I'll share now.

Since that time my son has bought his own new computer so I get to reclaim my old T520 and repurpose it downstairs in the kitchen.
However, that means I now need to address the Wi-Fi issue I initially encountered 1.5 years ago but which is still present.

The issue is this: The SSIDs from our AT&T router are not visible on the list of available Wi-Fi networks. Neither the main SSID or the 'Guest" SSID show up on the list.
All my neighbors SSIDs are present.
While I have not gone door to door taking a poll of my neighbors SSIDs (that would surely be weird), based on the sheer volume of SSIDs showing up, I feel safe in assuming they're all showing up as available on my T520.
When I turn the hotspot from my phone on, that SSID appears and I'm able to connect to it.

Additionally, my other laptop (Lenovo W540), my cell phone (Samsung Note 10+) and my son's cell phone (generic Samsung), and my girlfriend's IPhone are ALL able to see our SSID's (both of them) and are able to connect to them without issue.
So, whatever this is, it's apparently only impacting this one laptop (the T520).

Furthermore, assuming it might be a Windows issue I would've been perfectly fine with flattening all 3 of these partitions (one is just for storage) and doing a clean Windows install. However, in consideration of that idea I booted into the seldom used x86 partition believing I should see the SSIDs there and my path to solution would be clearly identified. However, I was very distressed to see that in-fact, NO, the SSIDs (neither of them) are also not present on the clean x86 partition either!

Diagnostics:
1. Turned off the Wi-Fi LAN option in BIOS. Booted to Windows to confirm and shut back down. Turned Wi-Fi LAN back on in BIOS and booted back to Windows - No Joy - No Change
2. Check for updated drivers - none were found and so no change
3. Booted into a clean x86 partition on the same computer and still not seeing the SSIDs
4. Removed the prior Wi-Fi network from "Wi-Fi Networks" in Windows and tried to manually add it back. No Joy - No Change
5. Spent the whole morning on the phone with AT&T support. We:
6. Factory reset the router (3 times) - No Joy - No Change
7. Looked for any configuration information that might be blocking this laptop's IP address or MAC address. - No Joy - No Change
8. Changed the SSIDs (both). We confirmed the new names were functioning on other devices but No Joy - No Change on the T520.
9. Connected the T520 to the router by ethernet cable and the AT&T engineer confirmed he's able to see it - He was able but still No Joy - No Change on the Wi-Fi side.
10. Purchased an exact OEM replacement internal Wi-Fi card and installed it - No Joy - No Change

So I feel like I'm out of gas here and need some extreme deep help here.
Is there anything in the registry that could be blocking discovery of these SSIDs but if so, how would that've impacted BOTH partitions?
Is there some way, any way, flattening these partitions and doing a fresh Windows install could fix this?
